CELLSIZE is the jCell module of jLab.

 CELLSIZE  Size of each element in a cell array along specified dimension.
 
    S=CELLSIZE(X,DIM) where X is a cell array of N arrays, is equivalent to
   
       S(1)=SIZE(X{1},DIM), S(2)=SIZE(X{2},DIM), ..., S(N)=SIZE(X{N},DIM)
 
    thus returning an N x 1 array containing the sizes of each element of X
    along dimension DIM.
 
    CELLSIZE requires the cell array X to have four or fewer dimensions.
 
    See also CELLENGTH.
 
    Usage: s=cellsize(x,dim);
